Anatomy ‘Wrong’ in Early Animals

Anatomy ‘Wrong’ in Early Animals

Textbooks might have to be re-written when it comes to some of the earliest creatures, a study suggests. Researchers have found that our understanding of the anatomy of the first four-legged animals is wrong. New 3D models of fossil remains show that previous renderings of the position of the beasts’ backbones were actually back-to-front. The findings, published in the journal Nature, may even change our thinking on how the spine evolved.
